AI Technical Summary

Benefits of technology

The system effectively applies the gel composition without clogging, ensuring stable powder suspension and long-lasting cosmetic application with improved transfer-resistance and long wear properties.

Problems solved by technology

Although such delivery devices are known, there remains a need for improved ways and systems to make-up and enhance the appearance of keratinous materials using gel compositions which can have difficulty flowing through delivery devices, which can preclude application of product using a delivery device owing to clogging, and which can have poor powder dispersion.

Example 1—Invention Compositions

[0151]The following composition can be prepared:

Product Applied

[0153]Protocol: 15 g of the formula of example 1 was placed into a 2 oz jar, and a porous polymeric material was placed into the 2 oz jar, and allowed to sit overnight. The porous polymeric material was then then applied to the skin 10 times, and the amount of product lost from the porous polymeric material during application was weighed.

[0154]Two different applicators were tested: one applicator having a porous material with a top portion having average pore size of about 40 microns; and one applicator having a porous material with a top portion having average pore size of about 100 microns.

[0155]The first applicator (pore size of about 40 microns) deposited 0.001 g / dab, which was perceived favorably upon application. The second applicator (pore size of about 100 microns) deposited 0.003 g / dab, which was perceived as being too heavy / too much product deposited.

n of Wicking or Capillary Effect of Gel Compositions

[0156]Identical compositions were prepared, except the invention composition contained 0.5% Aristoflex HMS and the comparative composition contained 0.5% Carbopol. Both gels were thick, with the invention composition having a higher viscosity.

[0157]However, when placed at the base of a porous polymeric material having a bottom porosity of 100-170 micron and a top porosity of 40-75 micron, the comparative composition (Carbopol) did not flow via capillary effect to the top portion of the porous polymeric material. Surprisingly, the invention composition (Aristoflex HMS) did flow through the porous polymeric material via capillary effect. The invention composition (Aristoflex HMS) had a sol / gel crossover point of about 45%, whereas the comparative composition (Carbopol) had a sol / gel crossover point of about 110%. The lower sol / gel point associated with the present invention resulted in low strain, allowing the Aristoflex HMS gel to b...

Abstract

The present invention relates to a cosmetic system comprising an applicator and a gel composition, and methods for making-up and enhancing the appearance of keratinous materials using the systems.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a cosmetic system comprising an applicator and a gel composition.DISCUSSION OF THE BACKGROUND[0002]U.S. Pat. No. 7,427,412, RU 128078, U.S. Pat. No. 4,050,826, EP 155350, US 2003 / 0129016, US 2014 / 0332026, US 2008 / 0083419, EP 1565326, DE 202012104020, U.S. Pat. No. 8,444,337, U.S. D 734,895, U.S. D 620,368, U.S. D 709,652, and U.S. D 401850 relate to delivery devices for formulations.[0003]Although such delivery devices are known, there remains a need for improved ways and systems to make-up and enhance the appearance of keratinous materials using gel compositions which can have difficulty flowing through delivery devices, which can preclude application of product using a delivery device owing to clogging, and which can have poor powder dispersion.[0004]Accordingly, one aspect of the present invention is a cosmetic system comprising an applicator and a gel composition which addresses one or more issues identified in the pre...
